In addition, an elevating device 20 that moves the storage container 15 in the vertical direction is provided inside the storage chamber 13.

  As shown in FIGS. 5, 6, and 7, the lifting device 20 of the refrigerator 1 according to the present invention includes a storage container support 73 that supports a storage container received in the storage chamber 13, and a storage container support 73. It has the raising / lowering part 70 which is provided in the lower side and supports the storage container support part 73, and the lower support stand 80 provided in the lower side with respect to the raising / lowering part 70. The elevating device 20 includes a drive motor 30 that is provided on a side surface of the lower support base 80 and generates a rotational motion, a rotary member 40 that has one end attached to the drive motor 30 and is driven to rotate, and the rotary member 40 and a screw. The rotational movement of the rotating member 40 is stored by coupling (a threaded portion 41 formed on the rotating member 40 and an internally threaded portion 63 formed so as to mesh with the threaded portion 41 and coupled with each other). And a rotation link 50 that converts the vertical movement of the container 15.

  The rotation link 50 is moved up or down depending on the rotation direction of the rotation member 40, and includes a slider 61 that is screw-coupled to the rotation member 40 and a link member 51 that is hinge-coupled to the slider 61.

  The link member 51 is a long plate having a bent portion 55 in the longitudinal direction, and only the bent portion 55 exists at both ends in the longitudinal direction. The link member 51 is formed with a pair of first hinge coupling portions 53 at one end of the link member 51 for hinge coupling with the slider 61. The first hinge coupling portion 53 is provided with a pair of opposed first coupling holes 56 a formed in a bent portion 55 extending from the end portion, and the pair of first coupling holes 56 a connects the rotating member 40. Facing each other. The 1st hinge coupling | bond part 53 is not restricted to embodiment, It can comprise in various forms. For example, the end of the bent portion 55 is

形状になっている第１ヒンジ結合部５３としても差し支えない。第１ヒンジ結合部５３が設けられる端部に折曲部５５だけが存在することは回動リンク５０が下降状態にある時、リンク部材５１とスライダー本体６２が干渉されることを防止するためのである。リンク部材５１の他端部には、昇降部７０とヒンジ結合するため一対の第２ヒンジ結合部５４が形成されている。第２ヒンジ結合部５４も端部から延長された折曲部５５に形成されている。第２ヒンジ結合部５４が設けられる端部に折曲部５５だけが存在することは回動リンク５０の下降時に昇降部７０とヒンジ結合する部分で一対のリンク部材５１が相互に干渉されないようにするためのである。第１ヒンジ結合部５３及び第２ヒンジ結合部５４は、連結部５２によって連結されている。 (Outside 1)

The first hinge coupling portion 53 having a shape may be used. The presence of only the bent portion 55 at the end where the first hinge coupling portion 53 is provided is to prevent the link member 51 and the slider body 62 from interfering when the rotary link 50 is in the lowered state. is there. A pair of second hinge coupling portions 54 are formed at the other end portion of the link member 51 so as to be hinge-coupled to the elevating portion 70. The second hinge coupling portion 54 is also formed in a bent portion 55 extending from the end portion. The presence of only the bent portion 55 at the end where the second hinge coupling portion 54 is provided is such that the pair of link members 51 do not interfere with each other at the portion that is hinge-coupled to the elevating portion 70 when the rotating link 50 is lowered. To do. The first hinge coupling portion 53 and the second hinge coupling portion 54 are connected by a connecting portion 52.

  The link member 51 includes a first link member 51a and a second link member 52b, which are hingedly connected by an elevating part 70 and a fastening pin 72, respectively. The elevating part 70 that is hinged to the link member 51 is formed with a coupling hole 71, and the coupling pin 72 hinges the link member 51 and the elevating part 70 while passing through the coupling hole 71 and the second hinge coupling part 54. Join. At this time, for the convenience of the hinge coupling, the distance between the pair of coupling holes 56b facing the second hinge coupling portion 54 is preferably slightly different between the first link member 51a and the second link member 51b. Unlike the embodiment in which the pair of link members 51 are both hinge-coupled to the lift unit, the first link member 51a and the second link member 51b may be hinge-coupled to the lift unit 70, respectively.

  In this way, one end of the link member 51 is lifted and lowered by the rotation of the rotary member 40 by hinge connection with the slider 61, and the other end is hinged to the lift part 70 and formed at the upper part of the lift part 70. The support part 73 is raised. At the time of lowering, the rotation direction of the rotating member 40 is reversed and the process of going up is reversed.

  A female threaded portion 63 for receiving the rotating member 40 is formed in the slider main body 62 of the slider 61. The female screw portion 63 is formed in a shape corresponding to the screw thread portion 41 formed in the rotating member 40 and is formed so as to penetrate the slider main body 62. The slider 61 is slid in the longitudinal direction of the rotating member 40 by the rotation of the rotating member 40 by the screw connection between the female screw portion 63 and the screw thread portion 41 of the rotating member 40.

  The slider 61 includes a substantially hexahedral slider body 62 and a pair of pins 65 that are screw-coupled to two surfaces facing the slider body 62. The pin 65 is hinge-coupled to the first hinge coupling portion 53 of the link member 51 so that the rotation link 50 can move stably.

  The pin 65 having such a function includes a head portion 66, a coupling portion 67, and a pin screw thread portion 68. The pin thread portion 68 is screwed to the slider thread portion 64 formed on the slider body 62 to fix the pin 65 to the slider body 62. The head 66 protrudes outside the guide rail 81 of the lower support base 80 and reciprocates along the guide rail 81 by the movement of the slider 61. The size of the head 66 is such that it does not come off the guide rail 81. The slider 61 and the rotation link 50 connected to the slider 61 operate stably without moving from side to side.

  Between the head 66 and the pin screw thread portion 68, there is a bar-shaped coupling portion 67 to which the first hinge coupling portion 53 of the link member 51 is hinge-coupled. A part of the coupling part 67 is hinge-coupled to the first hinge coupling part 53 of the link member 51, and the other part guides the slider 61 while making rolling contact with the lower part of the guide rail 81. That is, the coupling part 67 and the head part 66 become guided parts guided by the guide rails 81 provided on the lower support base 80. The guided portion supports the rotary member 40 on the lower support base 80 and prevents the rotary member 40 from moving in the lateral direction of the lower support base 80. The slider 61 also includes a first slider 61a and a second slider 61b that are hinged to the first link member 51a and the second link member 51b, respectively.

  Such a slider 61 can be variously modified. As in the embodiment, the link member 51 may be hinged through the upper surface of the slider body 62 without passing through the side surface of the slider body 62. Of course, in this case, not only the slider 61 but also the form of the first hinge coupling portion 53 of the link member 51 needs to be modified. Further, the head 66 of the pin 65 may be omitted. The shapes of the slider main body 62 and the coupling portion 67 are not limited to this embodiment.

  The rotary member 40 is formed in a bar shape having a circular cross-sectional shape, and a threaded portion 41a in a certain direction is formed in one half portion with respect to a substantially half portion in the longitudinal direction, and the other half portion is formed in the other half portion. A thread portion 41b in the opposite direction is formed. One end of the rotating member 40 is connected to the drive motor 30. The rotation member 40 and the drive motor 30 can be directly connected as in the embodiment. A gear is attached to one end of the rotation member 40 and the drive motor 30 is engaged with the corresponding gear. You can also At this time, the gear is preferably a helical gear.

  The drive motor 30 rotates when a power is supplied, and is provided with an output shaft (not shown) that is coupled to the rotating member 40 at one end and transmits a rotational force, and is connected to the drive motor 30. A switch 33 for rotating the drive motor 30 forward and backward is provided in an area of the main body 10 (see FIG. 3).

  The lower support base 80 receives the rotation member 40 and supports the rotation link so that the rotation link can stably move. The lower support base 80 has a long rectangular tube shape from which the substantially upper surface is removed. On both side surfaces in the longitudinal direction, guide rails 81 are formed by removing part of both side surfaces in the longitudinal direction. The guide rail 81 is divided into two parts 81a and 81b depending on the direction of the thread 41 of the rotating member. However, the two guide rails 81a and 81b may be connected to each other. A part of the coupling portion 67 of the slider 61 is bent on the guide rail 81, and a head 66 connected to the coupling portion 67 protrudes outside the lower support base 80 with the guide rail 81 interposed therebetween. The width of the slider 61 excluding the heads 99 formed on both sides must be slightly larger than the distance between the opposing guide rails 81. At one end of the lower support base 80, there is a rotating member passage hole 80 through which the rotating member 40 connected by the drive motor 30 passes. At the other end, there is a rotation member support hole (not shown) for supporting the rotation member 40.

  The guide rail 81 that guides the coupling portion 67 and the head portion 66 plays a role as a guide portion. However, the guide portion is not limited to the embodiment and can be modified in various forms. In other words, it is sufficient if the guided portion can be guided in the longitudinal direction of the lower support base 80, and can be provided separately from the lower support base 80.

  Accordingly, when an example of the assembly process of the lifting device 20 according to the present invention is seen, the female screw portion 63 of the pair of slider main bodies 62 and the screw thread portion 41 of the rotary member 40 are screw-coupled, and the slider main body 62 and the rotary member are thereby connected. 40 is combined. Since the screw thread portion 41 includes two portions 41 a and 41 b that are different in the direction in which the screw is wound, the pair of slider main bodies 62 are coupled from both end portions of the rotating member 40, respectively. At this time, the pair of slider main bodies 62 are located at the same distance centering on the place where the screw thread directions are opposite on the rotating member 40.

  The rotating member 40 on which the pair of slider main bodies 62 are mounted is fixed to the lower support base 80 using the rotation member passage hole 82 and the rotation member support hole (not shown) of the lower support base 80. After that, the link member 51 is provided so that the coupling holes 56 a of the pair of first hinge coupling portions 53 are located at the slider screw thread portions 64 formed in both pieces of the slider body 62, respectively. The connecting portion 67 is inserted into the pin screw portion 66 and the slider screw thread portion 64 is screwed. At this time, the pin 65 is coupled to the slider body 62 with the guide rail 81 formed on the lower support base 80 interposed therebetween. The link member 51 and the slider 61 are hinge-coupled by coupling the pin screw portion 66 and the slider screw portion 64, and the head portion 66 is positioned outside the lower support base 80 with the guide rail 81 interposed therebetween.

  The pair of link members 51 are hinge-coupled to the slider 61, and the coupling pin 72 is inserted into the second hinge coupling portion 54 and the coupling hole 71, whereby the link member 51 and the lifting / lowering portion 70 are hinge-coupled. By connecting the drive motor 30 to the rotating member 40 and positioning the storage container support 73 on the upper side of the elevating part 70, the assembly process of the elevating apparatus 20 according to the present invention is completed.

  As shown in FIG. 8, the link member 51 of the lifting device 20 according to the present invention is folded in the direction of the rotating member 40 and the lifting device 20 is lowered.

  As shown in FIG. 9, the lifting device 20 in which the link member 51 of the lifting device 20 according to the present invention faces the lateral direction of the rotating member 40 has lifted the storage container 15.

  With such a configuration, when the operation process of the lifting device 20 of the refrigerator 1 according to the embodiment of the present invention is seen, the lifting process of the lifting device 20 is attached to one region of the main body 10 and the driving motor 30 of the lifting device 20 When the connected switch 33 is operated, the output shaft (not shown) of the drive motor 30 is rotated as much as the switch 33 is operated, whereby the rotating member 40 connected to the drive motor 30 is rotated simultaneously. As a result, the pair of sliders 61 screwed to the rotating member 40 moves in the center direction of the rotating member 40, and one of the pair of link members 51 hinged to the slider 61 also moves in the center direction of the rotating member 40. To do. That is, the pair of rotation links 50 approach each other. Due to the movement of one side of the link member 51, the other side of the link member 51 that is hinge-coupled to the elevating part is raised, and the elevating part 70 connected thereto is also raised. Thereby, the storage container support part 73 and the storage container 15 in the upper part of the raising / lowering part 70 raise. Therefore, the user can easily take out the storage container 15 without bending down. At this time, a part of the coupling portion 67 of the slider 61 is moved in the central direction of the rotating member 40 by the guide rail 81, and the head 66 connected to the coupling portion 67 is also moved together. The coupling part 67 and the head part 66 prevent the pivot link 50 from moving left and right in the lower support base 80 and support the rotating member 40 screwed to the slider body 62.

  In the lowering process of the lifting device 20 for lowering the storage container 15, the switch 33 attached to one area of the main body 10 is operated to reversely rotate the drive motor 30, thereby reversely storing the storage container 15 in the order described above. Descends. That is, the pair of rotation links 50 are separated from each other. Therefore, the user does not have to bow down when the storage container 15 enters the storage chamber 13.

  Further, as shown in FIG. 8, it is also possible to produce so that the lifting device 20 excluding the drive motor 30 in the lowered state is received by the lower support base 80. In this case, the portion occupied by the lifting device 20 of the present invention can be very small. Thus, since the raising / lowering apparatus 20 of this invention can produce a low height, it can minimize that the bulk of the storage chamber 13 reduces.

  The elevating device 20 is received in the storage chamber 13 of the refrigerator 1, the connecting line between the drive motor 30 and the switch 33 is detachably connected (not shown), and is detachably provided according to the user's selection. The elevating device 20 can also be produced integrally with the main body 10 of the refrigerator 1.

  As described above, according to the present invention, there is provided a refrigerator capable of raising a storage container received in a storage chamber as long as the user wishes.
